Apollo drogue chute test 99-5 failed at the El Centro, Calif., parachute facility. The drop was conducted to demonstrate the slight change made in the reefed area and the 10-second reefing cutter at ultimate load conditions. The 5,897-kilogram vehicle was launched from a B-52 aircraft at 10,668 meters and programmer chute operation and timing appeared normal. At drogue deployment following mortar activation, one drogue appeared to separate from the vehicle.

This chute was not recovered but ground observers indicated the failure seemed to occur in the riser or vehicle attachment. The second drogue remained on the vehicle but seemed to slip in the reefed state. This chute was recovered and inspection confirmed the canopy failure. The Air Force parachute system which was to recover the vehicle also failed in the reefed state.
